Fish can also distinguish human faces, and if they know the person, they will react differently, especially if it is someone feeding them.
Some fish live longer than humans. Many species of fish that live in the deep sea can live for 30 years or more. Some deep-sea fish such as the orange roughy can survive in the seas up to 150 years old.
Because deep-sea fish are farther away from human influence and their growth processes are slower, their average lifespan is also longer than others. However, these species, which are usually endemic, can easily become extinct because they reach sexual maturity quite late.
